# How do I add an attachment to my invoice?

## Symptom

How do I add an attachment to my invoice?

## Resolution

To attach a document when creating an invoice:

1. Click **Add to Header** > **Attachment**.
2. In the added **Attachments** section, click **Choose file** and select the document.
3. Click **Add Attachment**.

Remember that the total size of all attachments cannot exceed 100 MB.

The following are additional considerations related to invoice attachments:

- Not every customer accepts invoice attachments. View your [customer's invoicing rules](https://support.ariba.com/item/view/142286) to see if attachments are permitted.
- Your customer might also limit the [type of files you can attach to invoices](https://support.ariba.com/item/view/155169).
- Suppliers commonly add a PDF \[Portable Document Format\] copy of the invoice and supporting documentation to their invoices.
- To delete a document that you added to an invoice, select the box next to the document, and click **Delete**.
- After you submit an invoice, you can edit the attachments only for invoices in [Canceled, Failed, or Rejected statuses](https://support.ariba.com/item/view/134103). For invoices in other statuses, work with your customer to decide how to send the attachments.
- If you are still unable to attach your document, verify that you are using a [certified browser](https://support.ariba.com/item/view/130899) and go through the [common browser troubleshooting](https://support.ariba.com/item/view/155094) suggestions.
- Please note: the file name should not include special characters. The only special characters allowed are period (.), hyphen (-), and underscore (\_). Please refer to the document *[Attachment File Names](https://help.sap.com/docs/business-network-for-trading-partners/cxml-solutions/attachment-file-names)*. Also, the file extension must be in lover cases (.pdf not .PDF).
